Quantum Speed Limits and the Ultimate Scaling of the Quantum Sensors [PDF]

Entropy
Quantum metrology promises sensitivity beyond classical strategies, yet it remains unsettled how quantum-enabled precision should scale with physical resources and how to interpret quantum advantage.

On the modeling of amplitude-sensitive electron spin resonance (ESR) detection using voltage-controlled oscillator (VCO)-based ESR-on-a-chip detectors [PDF]

Magnetic Resonance, 2021
In this paper, we present an in-depth analysis of a voltage-controlled oscillator (VCO)-based sensing method for electron spin resonance (ESR) spectroscopy, which greatly simplifies the experimental setup compared to conventional detection schemes.

A portable NMR platform with arbitrary phase control and temperature compensation [PDF]

Magnetic Resonance, 2022
In this paper, we present a custom-designed nuclear magnetic resonance (NMR) platform based on a broadband complementary metal–oxide–semiconductor (CMOS) NMR-on-a-chip transceiver and a synchronous reference signal generator, which features arbitrary ...

Skyrmion velocities in FIB irradiated W/CoFeB/MgO thin films

AIP Advances, 2022
In recent years magnetic skyrmions attracted great attention for the possibility to move them with low current density, their intrinsic stability and their robustness against defects and edge roughness compared to other magnetic textures.

Defect-induced monopole injection and manipulation in artificial spin ice

Nature Communications, 2022
Artificial spin ice systems offer a promising platform to study the motion of emergent magnetic monopoles, but controlled nucleation of monopoles is challenging.

How Secure Are Two-Way Ping-Pong and LM05 QKD Protocols under a Man-in-the-Middle Attack?

Entropy, 2021
We consider a man-in-the-middle attack on two-way quantum key distribution ping-pong and LM05 protocols in which an eavesdropper copies all messages in the message mode, while being undetectable in the mode.

Non-Kochen–Specker Contextuality

Entropy, 2023
Quantum contextuality supports quantum computation and communication. One of its main vehicles is hypergraphs. The most elaborated are the Kochen–Specker ones, but there is also another class of contextual sets that are not of this kind.

Surface Engineering of Silicon Quantum Dots: Does the Ligand Length Impact the Optoelectronic Properties of Light‐Emitting Diodes?

Advanced Photonics Research, 2021
Herein, silicon quantum dot light‐emitting diodes (SiQD LEDs) are investigated to explore the interplay between their electroluminescence (EL) blue shift and the SiQD ligand length on the SiQD surface.
